Title Assessing the quality of air used to feed supplied air respirators: Measurement of oil and carbon monoxide content
Original title Evaluation de la qualité de l'air utilisé pour l'alimentation des systèmes à adduction d'air: mesure de la teneur en huile et en monoxyde de carbone [in French]

Abstract The objective of this study was to examine the quality of compressed air from compressors supplied to wearers of respiratory protection devices. A field study was conducted in different industrial settings, including asbestos removal work, metal part sandblasting and fettling work in a foundry. A sampling and counting method for compressed air was developed, and oil and carbon monoxide concentrations were measured in the air either while it was coming out of the compressor or after it had gone through a cleaning device. The findings differed between sites, although serious exposures were encountered only on one site (and excessively high concentrations in air directly at the compressor on one other site). The responsibilities of the various industry participants (equipment hirers, employers and occupational hygienists) are described, and the need for special compressors for respirable air as well as the importance of maintenance and inspection procedures for this type of equipment are emphasized.
